Hi Kathir,
I don't know if that's posible, but seems like the better approach is to
just define your function to take two arguments.
What do you think?
Best,

Hi all，
Is a character set error？

Hi,
In UDF, in the implemented evaluate(tuple,ptr) method, i could access the
expression object of the columns passed to the UDF, by invoking
*getChildren.get(index)*. and then by invoking
expression.evaluate(tuple,ptr), i can get the value copied to the ptr
object. But, how do i access other
Hi Jaime,
In my case, the number of arguments passed to the custom function will be
different in different scenarios. I think UDF is designed to take fixed
number of arguments, i believe (also, I see number of arguments column in
SYSTEM.FUNCTION table).
Another question - As we have the row
+1 to Jaime's suggestion of providing multiple arguments. You can have
a variable number of arguments to a function by providing default
values for trailing arguments. I wouldn't rely on the Tuple argument
in the evaluate method as it might go away in the future
(PHOENIX-1887).
Thanks,
